AUTOMOBILE SIGNAL.

Application filed fl'anuary 27, 1922. Serial No. 532,151. 7

To all whom it may concern: v

Be it known that I, FREDERICK BAUER, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Automobile Signals; and I do hereby declare that the following is a full, clear, and exact description thereof. 1 w

The invention relates to an automobile signal. 7 plate; having, on both sides, thev words Iurn and Stop, a weight carried by the plate for ii'iai'ntainingit in a normally horizontal position, a lamp, a glass-bowlithru which the words .Stop? and Tam; are visible when the plate is moved from a horizontal position, cams on the plate and electromagnetic means cooperating cams for oscillating them in either direction to make visible the word Turn or the word Stop, if desired, and a lens for normal use in cooperation with the lamp as a tail-light.

Important objects of the invention are the provision of a device which may be used normally for tail-light purposes but is also adapted by convenient manual manipulation to operate as a stop or turn signal.

Another and important object is the elimination of friction, the plate turning merely on pivots and being operated solely by the" electromagnetic and gravitational forces, no

levers nor other mechanical operative parts being necessary, resulting in a and not be rendered inoperative as the result of wear. By reason of the non-frictional action, only small voltage will be required in the electromagnetic means.

An advantage is the utilization of the hold the plate horizontal, being operative when the gravitational inforce of gravity to the magnetic force desired to overcome fluence.

'An important advantage is the simplicity of construction, only one plate being utilized for signalling purposes.

With the above and other objects in view which Wlll appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the It comprises a pivotally supported.

Figure 2 is secured by scre ws with a 'socket'19, receiving lamp 20 on either with the the elimination of friction. device which will be durable herein disclosed invention may be made. as come within the scope. of the claims.

In the accompanying drawing, 1 have illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode I have so fardevised for the practical application of the principles thereof, and in which: i I y Figure 1 is a side elevation with part of thecasing and bowl in. section. 3 a cross section of the signal. Casing 110 may be securedsuitably to the vehicle by support 11, and isprovided with an annular flange 12 for the reception of white lens 13 and flange 14 for the reception: of red lens 15.- A horizontal flange 16'is inwardly directed to which a plate 17 is 18. The plate is provided side of which are positioned magnets 21, 21, from which electric leads 22, 23 and 24 extend to a pole of a battery, the other pole of which is grounded. Magnets 20 and 20, and lamp 20' are grounded. Conveniently manually operated switches may be provided for leads 22, 23 and 24a Casing 10 is provided at its lower edge with a rib 25 receiving flange 26 of glass bowl 2?, spring 28 operating to retain the bowl in position.

Plate 29, having the words Stop and Turn thereon, as shown in Figure'l, is

provided with sockets 30 receiving the ends of screws 31'directed thru rib 25, plate 29' being adapted to balance and pivot on these screws. lVeight 32 is adapted to hold plate 29 normally in a horizontal position in which case the device operates as a taillight, the illumination being apparent thru red lens 15. the face of plate 29, and are spaced apart, support 33 carrying arcuate member 35 and support 3st carrying arcuate member 36. When weight 32 is in its lowermost position, the actuation of magnet 21 exerts a pulling action on arcuate member 35 which is positioned immediately below magnet 21 and Supports 33 and 3 1 rise from I the curve of arcuate member 35 is such that in the movement of the parts tothe position shown in Figure 2, the arcuate member approaches closer and closer to magnet 21.

Figure 2 indicates the resulting position of stability. On the cessation of the mag netic force, plate 29 resumes a horizontal position. On the actuation of magnet 21', the plate moves in a reverse direction and reveals the word Stop, which is illuminated by lamp and visible thru glass bowl 27 I both for the illumination of the tail-light and of the remaining portions of the apparatus. The light is reflected from the interior of the casing and this reflecting light as well as the direot'light from the lamp fully illuminates the plate when it is rocked into either of its two display positions. e

I claim:

In an automobile signal, a casing, a lens carried thereby andv adapted for use as a tail light, a glass bowl supported by said casing and suspended beneath the casing, a plate extending across the casing and glass bowl, pivots carried in said casing for revolubly supporting said plate, a pair of arcuate members rigid with said plate and formed of magnetic material, said arcuate members being of different curvature through their ex? tent, a weight rigid with said plate and adapted to maintain it normally in a horizontal position, a lamp carried within said casing above said plate and adapted to illuminate said lens and said plate, a pair of clectromag'nets each positioned above an arcuate member, means for supporting said lamp and said magnets, said plate having signalling indicia upon opposite sides thereof, whereby said plate normally extends horizontally across the apparatus and shields said bowl from said light and upon energization of one of said magnets rocks into a vertical position to display one side thereof and the corresponding signalling indicia carried thereon.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

FREDERICK BAUER.
